Abstract

A 58-year-old female patient with a medical history of arterial hypertension and a negative family history for cerebrovascular diseases presented with a headache. MRI/MRA revealed an incidental aneurysm of the right internal carotid artery (ICA) at the origin of the anterior choroidal artery (AchoA) with a fundus diameter of 4.9 mm and a neck diameter of 2.9 mm. This aneurysm was given endovascular treatment in which a p64 flow diverter (phenox) was implanted. A follow-up DSA after 3 months showed the complete angiographic occlusion of the aneurysm with a minor in-stent stenosis. DSA runs 9 and 12 months after the endovascular treatment confirmed the persistent aneurysm occlusion, the preservation of the AchoA, and the spontaneous regression of the in-stent stenosis. Flow diverter treatment of AchoA aneurysms is the main topic of this chapter.
